(Cl.215-13) ABSTRACT OF THE DISCLOSURE A container including inner and outertelescopingly engaged tubular members closed at one set of correspondingends and open at the other set of corresponding ends with the open endportion of the inner tubular member being seatingly engaged with theinner surface portions of the open end of the outer tubular member andprojecting outwardly of the latter and the closed end of the outertubular member being inwardly displaceable by an inward force directedthereon from the exterior of said body and operable, when being inwardlydisplaced, to at least slightly outwardly displace the inner tubularmemher from the open end of the outer tubular member.

This invention relates to a novel and useful insulating tumbler assemblyand more specifically to an assembly including a generally tubular outerbody closed at one end and open at the other end. The assembly alsoincludes an inner tubular member which is closed at one end portion andhas its closed end portion removably telescoped into the open end of theouter tubular body with the closed end portion of the inner tubularmember disposed in the closed end of the tubular body. Further, the openends of the tubular body and tubular inner member include coacting innerand outer surface portions respectively, which are seated in frictionalengagement with each other in a manner forming a generally fluid-tightseal therebetween.

At least some portions of the inner tubular member are spaced fromcorresponding portions of the outer tubular body constructed ofdeformable material and adapted to be displaced inwardly by a forcedirected thereon from the exterior of the body to thereby reduce thevolume of the area disposed between the spaced portions of the outertubular body and the inner tubular member. In this manner the airpressure within the area will be increased and may be utilized to ejectthe inner tubular member at least slightly outwardly of the open end ofthe tubular body member.

Further, the deformable portions of the outer tubular I body form thebottom wall thereof and are convexed downwardly whereby the convexeclportions may be readily upwardly displaced in order to increase the airpressure within the above mentioned area. Still further, the bottom ofthe inner tubular member is spaced only slightly above the convexedportions of the bottom of the outer tubular body thereby allowing thedeformable portions of the bottom of the outer tubular body to alsoContact and upwardly displace the bottom of the inner tubular memberwhen the deformable portion is displaced upwardly.

Both the outer tubular body and inner tubular member of the assembly ofthe instant invention are preferably constructed of a material havinglow heat transferring properties such as plastic enabling the assemblyto be utilized to contain either chilled or heated fluids which fluids,because of the low heat transfer properties of the outer body and innertubular member and the spacing between major portions of the outersurfaces of the inner member and the inner surfaces of the outer tubularbody, will tend to maintain their respective temperatures longer.

The main object of this invention is to provide an insulating tumblerconstruction or assembly that is adapted to have either chilled orheated liquids disposed therein and consumed directly therefrom by theuser placing the open end of the tumbler assembly to his lips anddrinking fluid from the tumbler.

Another object of this invention, in accordance with the immediatelypreceding object, is to provide an insulating tumbler assembly which maybe utilized to contain either chilled or heated liquids to be consumeddirectly therefrom and which, because of its heat insulating propertiesand double container construction, prevents the outer surface of thetumbler assembly from sweating or the supporting surface on which thetumbler is disposed from sweating.

A further object of this invention is to provide an assembly inaccordance with the preceding objects constructed in a manner enablingthe inner member to be readily displaced at least partially outwardly ofthe open end of the outer member.

A final object of this invention to be specifically enumerated herein isto provide an insulated tumbler assembly in accordance with thepreceding objects which will conform to conventional forms ofmanufacture, be of simple construction and easy to use so as to providea device that will be economically feasible, long lasting and relativelytrouble free in operation.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FIGURE 8 is a top plan view of the bottom assembly utilized in bothillustrated forms of the invention.

Referring now more specifically to the drawings, the numeral 10generally designates the insulating tumbler assembly of the instantinvention. The assembly 10 includes an outer generally tubular bodyreferred to in general by the reference numeral 12 and a generallytubular inner member referred to in general by the reference numeral14.

The outer body 12 includes a body portion 16 which is generallycylindrical in configuration and a bottom assembly referred to ingeneral by the reference numeral 18. The lower end of the body portion16 is beveled as at 20 to define a circumfererntially extending bead 22and the bottom assembly 18 includes a generally cylindrical body portion24 including a circumferentially upwardly opening groove 26 in which thebeveled portion 20 and the bead 22 are removably interlockinglyreceived. Further, the body portion 24 of the bottom assembly 18includes a bottom wall portion 28 including a thick outer annularperipheral portion 30 and a downwardly convexed central portion 32. Thetubular body 1.: is constructed of any suitable material such as plasticand has poor heat-transmitting properties. The central portion 32 of thebottom assembly 18 may be deflected upwardly to the position illustratedin FIG. 4- of the drawings by applying an upward force on the centerthereof.

The inner cylindrical member 14 includes a bottom wall 34 closing itslower end and its upper open end is provided with a circumferentiallyextending shoulder 36 which faces toward the closed end of the member 14and is abuttingly engageable with the upper end edges of the bodyportion 16 when the member 14 is telescoped within the body 12 in themanner illustrated in FIG. 3 of the drawings.

The body 12 includes an outwardly projecting fixed bailtype handle 38disposed in an upstanding plane and which may be readily grasped by theuser of the tumbler assembly 10 when lifting the latter to drinktherefrom.

The outer surface portions of the inner member 14 disposed below theshoulder 36 are tightly telescoped within the upper end of the body 12and forms a generally fluidtight seal therewith. Accordingly, if coldliquids are poured into the inner member 14, the air within the areadisposed between the spaced portions of the body 12 and inner member 14is chilled thus creating a partially vacuum which tends to tightly drawthe inner member 14 into full seated engagement within the body 12. Inorder to provide a means whereby the inner member 14 may be at leastpartially ejected from the open end of the body 12, the central portion32 of the bottom wall 28 may be deflected upwardly to the positionillustrated in FIG. 4 of the drawings thereby reducing the volume of thearea between the confronting surfaces of the body 12 and inner member 14so as to increase the air pressure within the area and thereby forciblyeject, by increased air pressure, the inner member 14 from the body 12.

With reference now more specifically to FIG. of the drawings, there maybe seen a modified form of insulative tumbler assembly generallyreferred to by the reference numeral and which includes an outer tubularbody generally referred to by the reference numeral 12' substantiallyidentical in construction to the tubular body 12 and which has itscomponent parts designated by prime numerals corresponding to thenumerals given the same component parts of the body 12.

The inner tubular member of the tumbler assembly 10' is generallyreferred to by the reference numeral 14 and includes a bottom wall 34corresponding to the bottom wall 34 closing the lower end of the tubularmember 14 and which is seatingly received in the downwardly convexedcentral portion 32 of the bottom wall 28 and engageable by the latterwhen the central portion 32 is upwardly deflected as illustrated inFIGURE 7 to assist the increased air pressure in the space between thebody 12' and the member 14 in at least partially ejecting the member 14defines an outer circumferentially extending shoulder 36' correspondingto the shoulder 36 which abuts against the upper edges of the open endof the tubular body 12'. However, the tubular member 14' extendsupwardly from the shoulder 36 and terminates in an outturned anddownwardly directed portion 40 which overlaps the upper end portions ofthe tubular body 12.

The operation of the insulating tumbler assembly 10' is of coursesubstantially identical to the operation of the assembly 10 except thatthe free lower end portions 42 of the backturned portion 40 also form agenerally fluidtight seal between the inner tubular member 14 and theouter tubular body 12'. Thus, a double seal is formed between thetubular body 12 and the inner member 14.

When it is desired to eject the tubular member 14' from the body 12, itis merely necessary to upwardly deflect the central portion 32' of thebotom wall 28' whereby increased air pressure within the area disposedbetween the inner tubular member 14 and the outer tubular body 12 willcause the inner tubular member 14' to be at least partially ejectedoutwardly of the open end of the tubular body 12'. Further, the centralportion 32' may be further upwardly deflected so as to abut the bottomwall 34 and thereby physically assist in at least initially ejecting theinner tubular member 14. Finally, the inner tubular member 14 may beincreased in length so as to have its lower end cradled by the outerperipheral portions of the bottom wall 28 and the central portion of itsbottom wall 34 engageable by the central portion 32 of the bottom wall23.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.
